Carby Jets?

Can not take it with you when you die!

someone has a lot of misplaced faith in the longevity of chinese throw away engines...

anyways...jets are NOT sized on the size of the hole, but on the amount of FUEL THEY FLOW in a given time.

yes, a 78 may actually have a SMALLER hole than a 72... depends how LONG the hole happens to be as well...

at least, thats how mikuni does it, and well...mikuni does have a reputation for reason.

no manufacturing process is that consistent that each and every bit coming out of the machine is identical... not when .005 mm makes a BIG difference.

jets are numbered AFTER being drilled. (and reamed...they ream them too)

for what we do, with these engines... a plain old set of micro drills, be they metric or number types, suffices.

having both types on hand does allow one to get even finer...but why? why bother?

 

[Hello Moto!]

I just bought a jet kit. Gonna try and figure this s**t out man! I know I'm running rich and having issues towards full throttle. It almost sounds like boggy or four stroking past 15mph. Not sure but I WILL figure it out.

I didn't figure I would have to mess with a stinkin jet livin close to 1500ft in the land of OZ. I'm gonna give it a shot though!
